Day 24
Domains and DNS
Let's talk about web addresses!
Today's Lesson
A domain is a human-readable address for your website. Instead of `random-string.vercel.app`, you could have `yourname.com`. DNS is like the internet's phone book, connecting domains to servers.
Today's Tasks
- 1Understand how domains work
- 2Either: Add a custom domain you own, OR understand the process for later
- 3Explore Vercel's free subdomain option
Prompt to Use
Explain how domains work - how does typing a URL lead to my website? I [do/don't] have a custom domain. [If yes: help me connect it to Vercel. If no: explain what I'd need to do when I get one.]
Expected Outcome
Understanding of domains and DNS.
New Terms
- Domain
- DNS
- Subdomain
- A Record
- CNAME
Pro Tip
You don't need a custom domain to launch. `yourproject.vercel.app` works fine for learning and portfolios.
Coming Tomorrow
We'll handle environment variables in production.
P.S. Domains cost about $10-15/year. Worth it when you want a professional presence.
